To all whom #may concern.-

Be it known that I, GEORGE B. KELLY, of

Boston; in the county of Suffolk and State ofy specially preparedstrip,` or. sheet, called a stencil, whichnecessitates that such stencilshall be of a width and thickness much greater andV of stronger materialthan the sheet or strip of paper to be perforated for the music sheet,-making these stencils more or less bulky and cumbersome; and withalarge number of such stencil sheets on hand requiring a great deal ofVroom in which to store and keep them, Whereas in the present machine anyperforated sheet can be used for the stencil as for instance theperforated music sheet itself, and `therefore not requiring specialpreservation for stencils, enabling the machine for perforating thestrips or sheets to bemade much smaller, more compact, takingyup muchless room 'and at much less expense, advantages in the preparation ofsuch perforated music sheets las are obvious to parties interested insuch manufacture. y The invention consists substantiallyln combinationwith means for perforating strips or sheets of paper or othervsuitablesheet matef` rial, of a suitable wind or exhaust bellows, a series of.pneumatic bellows communicating therewith, and a series of electromagnets electrically connected therewith, and all constructedand-arranged-for operation O'n a sheet of paper or other' suitablematerial all substantiallyas-hereinafter described; and the invention`also consists .of the construction. and arrangement of parts in suchmachine all: substantiallyas hereinafter fully described.

In'the accompanying sheets offdrawin'gs is illustrated a machine. forperforating sheets of paper or other sutablematerial constructed 'chinescription herein.

In the drawings A represents a horizontal bed plate which rests on'legsor uprights B which support the various parts of the ma- Fig. 9

its upper side an upright box C having a 'chamber D, making a windchest, similar to On this bed at the left, is secured on a wind chest ofa reedlorgan, and'communieating by a passage E, through the bed plate Awith a bellows F, secured to the under side of the bed plate, andarranged-to be operated4 in the usual manner of operating bellows forreed organs, and in such manner as preferably to exhaust the air fromthe wind chest chamber D, and needing no particular de- This wind chestextends transversely onthe bed, and arranged centrally and vertical-ly,therein is a board GrV its upper part extending up through and a shortdistance above the-top H, of the wind chest, and connected by its twoends to the endsJ of the -wind chest and of a thickness to leave an airspace between its sides and the side -walls K of the wind chest andextending down nearly to the bottom of the bed leaving 'an air space Lthereunder,` between it and vthebed, which has free communication `withbothsides, and .into whichthe bellows passage E communicates. In thisboard G are a row of vertical air passages M, whichopen to the outsideat its upper or surface `edge as yshown in section in'Figs. 2 and 3, andin plan view vin Fig. 1, whichlpassages at their lowerends alternatelyextend to the rghtand left, through lthe side of the blocky as at a, andeach opening into a separate pneumatic bellows N vertically secured'toboth sides of the board in two horizontal rows.' The upper IOO rows ofthese pneumatic bellows have their movable boards, hinged at their upperends as at t, and the lower rows at their lower ends as at d, and eachmovable board has the usual escape air passage e. Each pneumatic bellowshas a separate spring P secured to a rail f of the board G, at its hingeend, the free ends g of the springs bearing upon the respective movableboard of its pneumatic bellows to keep it closed and in its normalposition. These pneumatic bellows are arranged on the board so that theywill be alternately in different vertical planes transversely along thelength of the board, one af ter the other, as shown, for one side of theboard in Fig. 4, where h, is the first bellows, m the third bellows, nthe fifth bellows,rthe seventh bellows; the second, fourth, sixth andeighth bellows being Von the other side of the board but on differenttransverse vertical planes, that is, `the second on a transversevertical plane between the first bellows and third bellows, the fourthbellows on a transverse vertical plane between the third bellows and thefth bellows, and the sixth on atransverse vertical plane, between thefifth bellows and the seventh bellows, and so throughout the wholeseries. This arrangement of the pneumatic bellows allows the airpassagesto be close together, to occupy a small space, substantially sothat four passages will .occupy the space along the length of the boardol" a width kof one bellows, whereas arranging the bellows all in onerow would separate the air passages `accordingly making `the board muchlonger, andconsequently the machine much wider.

`Q is a roll adapted `by its journals ttoturn in bearings in two crossbars R, secured to the wind chest `at each end, and S is anotherrolladapted by its journalsu to turn in bearings in the cross bars R,and extending from one roll to the other is a sheet, or strip of paperT, its ends attached to the two rolls, and

between the two it lays on and is arranged to pass over the uppersurface e of the boardG, over the open ends of the passages M, it havingperforations w through it, and which sheet is the stencil, or patternsheet for the present machine. `Thisstencil sheet o r pattern isperforated in accordance with the musical tune as desired, and can be ofa width to have as many longitudinal rows of perforations as there areair passages M in the board G, the longitudinal rows of perforationsbeing the same distance apartas the air passages M. At the opposite endof the bed plate are secured two nprights U, one each side ofthe same,and between the two, a

is a plate or bar Vset up edgewise, arranged to slide up and down ingugideways a: on the innerlside of each upright U. Pivoted tothe under.edge of this plate at a are two ytoggle 1 levers "W, each near the endVof the plate, which are pivotedby their lower ends" at b to across barY of the bed A. Pivoted `by one end to the central pivot d of eachtoggle lever is a rod B', which by its other end is pivoted to a crankarm C of a horizontal shaft D' adapted to turn in bearings e secured tothe uprights. This shaft extends beyond the upright at one end andoutside thereof has a pulley E secu red thereto having a belt F which isarranged to be connected to any suitable driving power for operationthereof. Rotating the shaft Dv the toggle levers W at their centraljoint are moved forward and backward of the central vertical plane ofthe bar V and in such movements the bar is moved up and down,it1nov ingup and down twice to each revolution of the crank shaft. Above thismovable bar are a series of bars or rods G arranged in a horizontalplane, each arranged to slide back and forth in separate `guideways orvertical slots c in two plates f g arranged transverselyof the bed andsecured by their ends between and to the two uprights U.

In the under side or edge of each slide bar G is a notch h' through itsthickness which is longer than the thickness of the movable bar V, andwhen `these slide bars G are in their normal positions the notches arejust above the upper edge of the movable bar, and the notches are ofsuch depth that if the bar is moved up to its highest point it willenter the notch, but be free of and not touch the lslide bar, as showninsection fin FigrS, butif thisslide bar is moved forward intotheposition shown in Fig.i5, and the baris then raised the part m of theslide bar beyond the notch then beingover the bar V, it will cause the`slide bar to rise with it.

Attached to the rcarend of `each slide G `bya link e2 is the free end ofaseparate spring R secured by its other end to cross barS of theuprights. Aboveeach ot' theseslide bars is anyupright punch or die lIeach of which is arranged to move freely up and down in a separate slotor guideway n' in a cross bar J of the uprights.

`The upper portion of `each punch is smaller incross section and extendsupinto a socket `or opening fr in a horizontal ,plate K secured to thecross bar s which smaller portionleaves .on one side a shouldert' onwhich rests the free end u of a `flat spring Lsecured at 'v' to ,a crossbar M of theuprights, which bears and presses the punch down toitsnormalposition which is `when a projecting pin w' of the punch rests on across `barN and in such position the punch is a slight distance abovethe sliding bar G as shown in side view in Fig. `8, so it will not touchor rest thereon. `Resting on top of the plate K is a cross bar P havinga central longitudinal slot Y `through it, and a plate Q on its underside provided with a series of openings c2 therethrough, which are j ustoveror vertically co-` incident with the openings r in `the under plateK. 'This plate Q `is the die plate` and4 it and its bar P have twovertical holeswhich fit over `vertical pins d2 on the plate K', by`

which the upper bar with its die plate is ICO IIO

placed in proper position over the lower bar. Between these two plates KQ is arranged to travel in the direction of the arrow u2 the paper sheetT which is to be perforated which passes to and winds upon a rollUturning in bearings in the cross bars V. This roll has its journal f2extend beyond the cross head and on its outer end has asprocket wheel Wwith which engages a sprocket chain A2 which chain engages with anothersprocket wheel B2 secured tothe journal tof the rollU at the other endof the machine, carrying the stencil or pattern sheet. l

C2 are electro magnets and they'aresecured respectively to the one side,Fig. 2, of yfour separate transverse. upright boards D2 of the bed A. l

In the drawings there are only tive electro magnets shown, but in thepractical operation of the machine there are as many as there are airvpassages M in the board G, but only five'are deemed necessary to showin the draw'- ings,'more would only be duplicates.

Pivoted at g2 respectively tol three of the upright boards D2 andanother upright board E2 are vertical arms or levers F2 to the lowerpart of each of which is secured centrally at h2 an armature G2 which islocated in proper position for the electro magnet in front of it. Theupper end of each lever F2 is connected by a pin m2 to one end of astrip or rod H2, which is connected by its othergend by a pin n2 to theend of a slide bar G. This connecting strip is of a length, that whenconnected to an armature lever F2 and a slide bar Gr, the slide barspr-ing R will hold the slide bar back and Kthe'lever so that itsarmature will be away or: n disconnected from its electro magnet, whichis itsnormal position, as shown in Fig. 2, and in such position thenotchof the slide bar will be directly above the plate Vias shown in Fig'.'8.

Opposite each screw r2 securing the pneumatic bellows spring P as shown,in Figs. 2

and 3, is aI plug J2 having a headA t2 which closely ts in a socket u2in the side-board of the wind chest, and extends a short distancetherein and passing through it is an electric f wire K2 the endg beingcoiled a little as at @2,

l 5sA and when the plug is in place, bearing upon the head of the springscrew r2.

L2 is a screw screwing. through the wind chest side board in to thechamber and in line verticallywith a pneumaticbellows spring` P andoppositeto its free end as shown in section in Figs. 2'and3'. To eachofthese screws p L2 isconnected a separate electric wire M2,

and these screws with the springs P, are thev electr'odes,"and theseparate-wires are connected with an electric battery to make anelectric circuit.

With the stencilstrip T upon theroll S andv ,connectedv by one end tothe other roll Qand `the strip T of paper on its proper'rolls'to beperforated in` accordance with th'e'stencil.`

strip, and with the electric circuit all complete, the machine is readyfor operation. v

The main bellows F are operated in the usual manner which exhausts airfrom the wind chest, causing all the pneumatic bellows to close. Motionis then communicated to the pulley P2 causing the roll Q to turn whichdraws the stencil strip over the upper surface of the board G in thedirection of the arrow 102 Fig. 2 and winds it upon the roll Q; at thesame time through the sprocket wheel B2, chain A2 and sprocket wheel Wof the roll'U motion is communicated to it in the direction of the arrowy2 Fig. 2, which causes the paper strip to travel between the plates K Qover the perforations in the lower plate, and which moves with the samespeed that the stencil sheet does over the air passages, the two rollsand their sprocket wheels, being of corresponding diameters. The crankshaft D is also revolved at the same time which causes the board toreciprocate vertically and preferably quite rapidly. As the stencilstrip travels over the board G, and a perforation w, therein, comes overan air passage M, air vpasses quickly down through it into the pneumaticbellows N, with which it communicates, opening the same, which pressesits ,spring P back against the screw L2 making electric circuit, bywhich the `electro magnet infsuch circuit attracts its armature,swinging its lever F2 on its pivot, the upper arm of the lever pullingupon and moving the slidebar G for- VWard against its spring until itsnotch h. is

moved away from, and its thick portionm in the' next upward movement ofthe'board U pushes'the notched bar upward` and forces 4the punch pH upand through the paper sheet T making a perforation therein; as soon asthe perforation w in the stencil sheet passes by the air passage and theunperforated poris cutoff fromentering the passage which y over, themovable reciprocating plate U which tion of the stencil sheet comesthereover, air

circuit, closing its bellows and releasing thev armature to the electromagnet, allowing the spring of the slide bar to return it to its normalposition, with its notch over the movable board so that the next upwardmovement of the board, i-f a perforation'w, is not over the airpassage,will-not operate upon the punch,

but when the next perforation tu, comes over the air passage as before,the partsare again operated as described and another perforationv madein the paper sheet T and so on. Thus whenever a'perforation in thestencil sheet comes over an air passage in the board G, a correspondingperforation is made in the paper sheet T as described. l' i Intheupright board of each armature is ay screw m2 projecting therethroughagainst the end of which the armature lever abuts, when `away from themagnet to limit its backwardv movement, and by which such movement can'be regulated by'turning thel screwin or out.

The spring to each pneumatic bellows is bent so that when its free endis bearing upon the bellows, its other end, back of its securing screwwill bear upon the cross bar, the part where the screw passes through itbeing bent so that it is raised from the bar, so that by turning thescrew in or out lthe pressure ofthe spring can be increased ordiminished as desired upon the bellows, and when desirous of regulatingthe spring, pulling out the plug .I2 it can easily be reached by a screwdriver, and when turned as desired, the plug is inserted again andelectric connection `made with the spring as before. This isadvantageous, as it makes an easy and convenient way of regulating thepneumatic bellows springs.

The rear end of the notch in each slide bar is beveledias atau2 so thatif the slide har is pulled forward when the bar is moving upward, itwill easily ride up over its edge in its forward movement, so the barcan operate upon it.

In order to use a narrowstencil sheet, or the perforated music sheetwhich is quite narrow, and therefore reduce the width of the machine,the pneumatic bellows are ar-` rangedxin two horizontal rows on bothsides of Lthe air passage board, and in the order stated,and theelectromagnets are arranged in four rows on four separate supports, and theirarmature levers correspondingly, which brings them allcompactly togetherlaterally, and all connections between the air passages and the punchesin parallel lines, or substantially so. Each electro magnet is connectedelectrically to a separate pneumatic bellows, substantially as follows;looking at Figs. 1 and 6 more particularly; the first magnet a3 in thefirst row with the iirstpneumatic bellows m, and its lever with thefirst punch a4; the first magnet ha of the second row, with the secondbellows, and its lever with the second punch h4; the first magnet d3 Ofthe third row with the third bellows n and its lever with the thirdpunch d4; the first magnet e3 of the fourth row with the fourth bellows,and its lever with the fourth punch et; the second magnet f3 of thefirst row with the fifth bellows fr, and its lever with the fifthpunchf; soon with the second magnet of the second, third, and fourthrows, the third magnet of the first row, and so on throughout the wholeseries, there being as many magnets in the four rows as there are airpassages in the board.

.If desired the pneumatic bellows can be arranged in a larger numberofrows, also the electro magnets, which .would obviously reduce the widthof the stencil, but the arrangement described and shown is satisfactoryin its results.

The cross bar P having the die plate Q is held firmly in any suitablemanner from upward movement so that it will hold the paper T against thepunch in its Operation.

Having thus described my invention, what I claim is l. In a machine forperforating sheet maon said punch and a plate or bar adapted to move u pand down in suitable guideways for operation on said slide bar for thepurpose specified.
